How to use the ultrosonic sensor.
1. Click on the stopwatch icon.
2. Drag the icon with the ultrusonic sensor into your program.
3. Right click it.
4. Go to the help button.
5. Open the example.
6. Copy and paste it into your program, and you're done!



So you built the sensors on your robot? Great... but now you have to program the sensors. Here's how you do it. 1. make sure you're in inventor 4 2. click on the orange circle with the question mark on it in the functions panel this will bring you to a menu with pictures of a bunch of different sensors. 3. click on your sensor and drag it into your program. 4. now you have to add a numerical constant to it. to do this click on the little thing that says A1. it is at the far right of the ninth row of the functions palette. this will bring you to a page called modifiers. click on the one that says 123 on the far right of the 2nd row. this is called a numerical constant. attach it to the bottom of the sensor you just put in your program. 5. now put a number in the numerical constant. This isn't just some random number it means a bunch of things. If you attached it to your sound sensor the number represents the number of decibels the sensor responds to. If you connected the numerical constant to the ultrasonic sensor (the little head thing) it repreesents the distance something is to respond to. 6. add something at the end for the sensor to make something to do. when you're done it should look something like this.

I forgot to list some troubleshooting things.
here are some reasons why the head sensor didn't work on first 3 tries or so
1. we moved the thing blocking the sensor too quickly
2. the robot moved a liittle bit to the side a saw the wall
3. the numercial constant we put in was to big
hope that this helped with your sensor problems



6th grade,
If you are planning to write a song on the piano player here are the steps to getting it on your program.
1. Click on projects, on the tool bar, then click on "Piano Player".
2. Write your music by clicking on the keys.
3. To save your music click on the button bottom left corner that has a blue square inside a white square. Name your song and save it to the folder my songs, which will pop up.
4. Close piano player and go to your functions tool bar, click on the icon that looks like piano keys, this is only found in inventor 4 mode.
5. The functions tool bar will come up with a bunch more piano keys under them is the blue square inside a white square. Click on it and put it where you want in your program.
6. When you are ready and you click the arrow your documents will pop up, click on the folder with your song in it and then click on your song.
7. You are ready to go, the song does not need a time.



You have to first go to the icon panel thing, then click on structures --> task split
Then tell what you want to do on one end of the task split icon: ex. go forward for six seconds
and on the other send of it, tell the other thing that you want it to do: ex. sing the ABC's
at the end of both of the tasks you want to do, put a stop sign to tell it to, well... stop. Then you could keep doing what you want it to do!



When you program the robot you will want to make it do things for a certain amount of time. This is how you make it go for a certain amount.
1. Go to the panel that has all of the commands for the robot.
2. Click on the stopwatch with a ? on it.
3. Select a time or click on the other stopwatch with a ? and insert the button that you want into the program.
4. (This step is only if you chose the 2nd button with a ? on it) Type the time you want into the number below the stopwatch once it is inserted.moz-screenshot-1.jpg



My group and I were trying to put music on our robot, and it was not working. What we had done was that we had went into inventor four and went to projects and then piano. We had put in the Charlie brown theme song, and then we didn't know how to put it into our line of actions for our robot. We finally found out that you go into inventor four, click on the keyboard symbol, and a lot of notes, rests, and scrolls come up. You then drag the notes in the order that you want them into your line of actions. If you want rests, you drag the rest symbol in with the notes: after the note you want the rest after and before the note you want the rest to be before. When you are finished dragging your notes, then you can just put activities for the robot right after the notes without a stop-sign or anything. Finally, you click the white arrow when you are done with your whole line of actions for the robot (including the music,)and download them to your robot. That is how we got the Charlie Brown Theme Song on our robot!!!



when you add lights to your robot it make it really colorful especially when u put the two or three see through bricks over the lights. Connect the wire that is coming out of the lights and connect it to one of the bottom inputs of the main brain. Then, find the light icon which is probably near the the different sensor icons. Put it anywhere in your program, load it up onto your robot and hopefully it will work.



It has been hard to get it to move straight but we have figured it out. You need to plug the wire's into the correct places. Say you pluged them into A and B. You would have to, on the robolab sheet, have 2 forward movements. One A forward and one B forward. If you do not have both of the forward buttons, your robot will spin around in circles.
